| Abstract | Geological formation well-core sequences measured for porosity φ and permeability κ show a clear linear trend, logκ ~ αφ, when plotted as an ordered sequence in porosity. For porosity expressed as a fraction of rock volume, 0 less than φ less than 1, the observed proportionality constant α is of order 20 less than α |
